First off, I am studying neuroscience. From the research I did on the ingredients, they are in effective doses in this can. The studies tended to be on daily usage over a period of time, which means drinking these may not provide an instant productivity boost, and it would require one or two a day for a bit. Having said that. I went into trying these very skeptical. I assumed that they would be about as good as sugar free monster energy drinks. The taste is not great. However, if you need a 12 hour study binge for stem finals, these probably do more than monster energy. It might be the placebo, but the effect seems far too strong. These don't merely give you energy (which can lead to slacking off) they also give focus to the energy boost. This makes them (in my opinion, assuming it isn't the placebo effect which I don't think it is) better than sugar free monsters, and for the same price. TLDR: the taste is bad. They improve focus noticeably, and also provide an energy boost through caffeine (making them better than other energy drinks). I would absolutely recommend for other stem majors. Edit note- they have a tendency to sometimes fizz up when you open them, even if they have been sitting still for days. Careful if opening in the college library bc you might find a lot of people looking at you and need to find some paper towels
